Allelopathic impact of Parthenium hysterophorous L. on Sorghum bicolor and Zea mays

In this writing studies on weed, allelopathy and allelochemicals have been made and the present study suggests that Parthenium hysterophorous L. affects the agroecosystem and needs careful attention. Weeds continuously affects the growth of crops plants present in its vicinity. These unwanted plants needs carefull attention to have a greater yield of the crop in which it grows. These unwanted plants called as weeds releases harmful biochemicals known as allelochemicals in their vicinity that affects the growth and reproduction capacity of the growing crop that area. Parthenium hysterophorous L. being a declared invasive weed is threatening the biodiversity world wide. However, the extracts can be used as a viable weed management technique, but further studies are needed to explore the full potential of Parthenium as a bioherbicide.
